This rar-file contains all websites I could find on Sep 16th and 17th 2017 about Seiken Densetsu: Friends of Mana, a pre-Smartphone mobile game that was released in Japan in 2006. Its service ended in 2011.
Amongst the websites are three wikis about the game, containing a lot of stats of things, a few articles from magazine websites (like Famitsu), a few personal game diaries and a lengthy 2channel thread about this. So there's a lot of material of varying quality; I did not preselect anything (which would have been difficult since the overwhelming majority of the material is in Japanese and I cannot understand Japanese), I tried to collect everything that was at least remotely connected to the game. Several homepages may have been downloaded twice; I loose the overview everytime I go down that google search rabbit hole. This archive is meant as a foundation for research and restauration of this game that is virtually lost.
This archive contains also some websites with screenshots of the Seiken Densetsu: Final Fantasy Gaiden mobile remake of 2006 (which never left Japan, not to be confused with Adventures of Mana, the iPhone remake of 2016) and Front Mission 2089-II, because they were released around the same time, but the focus was definitely on Friends of Mana.
Something that is not included, but might me worth mentioning for future researchers: These games were presented on the Tokyo Game Show 2006, so may be there is some video footage of these games buried in some shaky cam material on Youtube/Nicovideo/Dailymotion/...
This archive also contains the material I uploaded in the "Friends of Mana Screenshots" bundle. You don't have to download that one if you download this one.
